                                                                     -----------


                         DIRECTOR-SHAREHOLDER AGREEMENT


     THIS DIRECTOR-SHAREHOLDER AGREEMENT ("Agreement"), is made as of this 5th
day of November, 2004, by and between First National Bank of Northern
California, a national banking association ("FNB"), and the director-shareholder
of Sequoia National Bank, a national banking association ("SNB"), whose name is
set forth under "Director" on the signature page hereof (the "Director"). FNB is
contemporaneously herewith entering into agreements with other
director-shareholders of SNB, which agreements are identical in all respects
hereto, except as to (a) the number of shares of SNB's common stock, par value
$1.00 per share (the "SNB Stock") owned by such other director-shareholders, and
(b) the name and address of the other director-shareholders. The Director and
such other persons shall hereinafter be referred to as to the "Directors" and
this Agreement and such other agreements as the "Director-Shareholder
Agreements." This Agreement is made with reference to the following:

     WHEREAS, that certain Acquisition Agreement (the "Acquisition Agreement"),
dated as of November 5, 2004, entered into by and among FNB, SNB and Hemisphere
National Bank, a national banking association ("HNB"), provides for the
acquisition by FNB of one hundred percent (100%) of the SNB Stock, through the
consolidation (the "Consolidation") of SNB with SNB Interim National Bank, a
national banking association to be organized for the purpose as a wholly-owned
subsidiary of FNB (the "Interim National Bank"); and

     WHEREAS, as a condition precedent to the obligations of FNB under Sections
7.1(d) and 8.2(j) of the Acquisition Agreement, the Director and all the
Directors shall have entered into Director-Shareholder Agreements concurrent
with the execution of the Acquisition Agreement, in accordance with the terms,
conditions, and provisions thereof;

     NOW, THEREFORE, in order to effectuate the transactions set forth above and
in consideration of the mutual covenants, conditions, agreements,
representations and warranties contained herein and in the Agreement, and
intending to be legally bound, the parties hereto agree as follows:

                                    ARTICLE I

                              COVENANTS OF DIRECTOR
                              ---------------------

     1.1    Vote of Shareholders. At the meeting of shareholders of SNB referred
to in Section 7.1(d) of the Acquisition Agreement (the "Meeting"), the Director
shall vote or cause to be voted the shares of SNB Stock indicated as owned or
controlled by such Director in Schedule I attached hereto, and any other shares
of SNB Stock now owned or hereafter acquired or controlled by such Director, in
favor of, and to approve the principal terms of, the Consolidation and the

                                       47


Liquidation and any other matter contemplated by the Acquisition Agreement which
requires the approval of the shareholders of SNB.

     1.2    Other Contracts. From and after the date of this Agreement, the
Director shall not enter into or become subject to any agreement or commitment
which would restrict or in any way impair the obligations of the Director to
comply with all the terms of this Agreement, including, without limitation, any
other agreement to sell, transfer or otherwise dispose of the Director's shares
of SNB Stock.

     1.3    Updating Information. In the event that the Director shall discover
that any representation or warranty made herein by such Director was false or
misleading in any material respect when made or that any event has occurred such
that any representation or warranty of the Director made herein would, if made
at and as of the time of the occurrence of such event, or thereafter, be
incorrect in any material respect, the Director shall deliver to FNB a statement
specifying that it is delivered pursuant to this Section 1.3 and stating in
reasonable detail the facts with respect thereto. Delivery of any such statement
shall not limit any rights which FNB may otherwise have under this Agreement.

     1.4    Agreement to Recommend. The Director agrees that, upon the execution
of this Agreement, the Director shall at all times use his or her best efforts
in order to obtain the approval of the shareholders of SNB of the principal
terms of the Consolidation and Liquidation, and any other matter contemplated by
the Agreement which requires approval of the shareholders of SNB, and shall
recommend the approval of such matters by the shareholders of SNB at the
Meeting; provided, however, that the terms of this Section 1.4 shall not apply
in the event SNB receives a qualifying "business combination" (as defined in
Section 7.1(a)(x) of the Acquisition Agreement) with respect to which SNB's
Board of Directors shall have determined, after consultation with SNB's counsel,
that action by the SNB Board of Directors under the fiduciary duties owed by the
Board of Directors to the holders of SNB Stock, which determination has been
made acting in good faith and on the basis of a written opinion from a financial
advisor retained by SNB to the effect that the financial terms of such
qualifying "business combination" (as defined in Section 7.1(a)(x) of the
Acquisition Agreement) are, from the perspective of SNB shareholders, superior
to the Consolidation, Liquidation and other transactions provided by the
Acquisition Agreement.

     1.5    SNB Stock Options. The Director agrees: (i) not to exercise any
outstanding SNB Stock Options granted to and held by the Director (the
"Director's Options") as of the date hereof and as set forth in Schedule II
attached hereto; and (ii) to sell the Director's Options to SNB in accordance
with Section 1.8 of the Acquisition Agreement. The Director further agrees that
any of the Director's Options not sold to SNB pursuant to Section 1.8 of the
Acquisition Agreement prior to the Effective Time shall expire at the Effective
Time.
